Sonoff for button (pulse) and not switch

I bought many Sonoff and some Sonoff PRO. My light system uses switching relay which work with a (just a pulse) button. How can I do? Somebody can help me? 

There is an easy way to  enter in the management software and set pulse and not switch?

Some advice?

Thank you

Sending a pulse with the Sonoff basic would be great!

Sorry Cristiano Pereira, can you explain better?

You can read here (even in Italian wiring diagrams should be self-explaining):

Actually I found that this is already implemented. In EweLink go to the device setting and set the inching enabled, make the time 0.5s and we have a pulse. Thank you itead for that !

But that enables pulse for all the buttons. That is the problem.

Merci beaucoup à Christiano Pereira !

It's OK.

"Inching" is not very good definition in french to say "Impulsion"
